CHARLES RUTSON, OF JACKSON, MICHIGAN, ASSIGNOR TO JACKSON CUSHION SPRING COMPANY, OF JACKSON, MICHIGAN.

SPRING- CONSTRUCTION.

Application filed September 3, 1908.

To all whom it may concern:

Be it known that I, CHARIJns RU'rsoN, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Spring Constructions, of which the following is a specification.

This invention relates to spring constructions.

One object is to provide a spring construction for automobile or other seats embodying such characteristics that the rider of the structure will not be injured or inconvenienced by reason of contact with the sup port upon which the structure is mounted in the event that the seat should be jarred incident to the weight of a heavy rider or in the event of the vehicle contacting with an obstruction in the roadway.

Another object is to reinforce the main springs of the structure with one or more single or compound auxiliary springs adapted to be compressed when the structure is subjected to unusual weight, whereby the auxiliary springs will catch the extra weight and prevent the structure from being wholly compressed.

With the above and other objects in View, the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details without departing from the spirit or sacri ficing any of the advantages of the invention.

In the drawings :Figure l is a plan view of the invention. Fig. 2 is a transverse sectional view. Fig. 3 is a detail perspective view of one of the auxiliary reinforcing elements. Fig. 4 is a fragmentary sectional view through the structure illustrating one end of one of the arch springs mounted upon its supporting means.

Referring now more particularly to the accompanying drawings, the reference characters 1 and 2 indicate upper and lower edge wires, which may be rectangular in formation or which may have one end curved, as indicated at 3.

If the cushion is formed round at one end, as shown, there will be a curved supporting Specification of Letters Patent.

wire 4: adapted to cooperate with the curved lower edge wire 2 for the support of the forward main springs 5.

Cooperating with the rear end of the structure is a supporting wire 6 upon which and the rear end of the lower edge Wire are mounted the rear main springs 5, there being pairs of supporting wires 7 arranged between the aforesaid supporting wires 4 and 6 for the support of other main springs 5. These supporting wires may be disposed Within the frame formed by the upper and lower edge wires in any suitable manner and the springs may be secured in place at their lower ends by means of suitable clips 9 and at their upper and lower ends along the border or upper edge wire by means of suitable clips 11. The clips employed in connection with the springs are not claimed in this case, and it will be understood that they may be of any particular variety.

Between certain of the main spring supporting wires are arranged auxiliary supporting elements a including spaced parallel members 10, and these auxiliary supports may be secured to opposite sides of the lower edge wire by means of suitable clips 11.

Slidably mounted upon each auxiliary support a is a series of short fiat spring metal elements forming arch springs 12, each arch spring 12 of each series havlng its opposite ends directed downwardly, as indicated at 1.3 and provided with a pair of perforations 14 adapted to embrace the parallel members 12 of the respective auxiliary support wires, whereby the arch springs may slide independently or together upon the auxiliary support wires when the structure is subjected to heavy weight.

It will be seen that the arch springs have their intermediate or highest points terminating short of the upper convolutions of the main springs so that if the main springs are subjected to a light pressure, the auxiliary arch springs will not be compressed at all, but only when the main springs are practically completely compressed, thereby preventing the heavy weight of the rider from passing below the lower edge wire. \Vhen these auxiliary arch springs are compressed their ends slide upon the auxiliary support wires and their bodies move toward and sometimes rest upon the auxiliary support wires.

If desired, I may secure the lower ends of within the frame.

a second set of auxiliary springs 15 to the backs of the auxiliary arch springs by means 5 of a suitable fastening 16. This second set 1 of auxiliary springs 15, as shown, are of the cone variety with their apexes secured to j the arch springs, but if desired, the position of the second set of auxiliary springs may obviously be reversed. In any event, the tops of the second set of auxiliary springs terminate below the upper convolutions of the main springs, so that the double set of auxiliary springs may catch the extra weights for the purposes stated. At any rate, when the auxiliary set of springs 15 are compressed, it follows that the other set of auxiliary springs 12 are compressed, but neither set of auxiliary springs are compressed until the main springs have been subjected to unusual weight.

From the foregoing, it will be understood that the second set of auxiliary springs may be dispensed with, and I also wish it understood in practice that the arch auxiliary springs may slide into abutting relation as regards the arch springs of each series when compressed, or be separated from one another at such time or when not compressed.

What is claimed is 1. A spring construction comprising a frame, main springs mounted within the frame, one set of auxiliary springs mounted between the main springs, and another set of auxiliary springs connected to the first mentioned auxiliary springs for cooperation with the latter to catch the extra weight.

2. A spring construction comprising a frame, main springs mounted within the frame, a set of auxiliary arch springs mount ed within the frame between the main springs, and another set of auxiliary springs connected to said arch springs for cooperation with the latter to catch the extra weight.

3. A spring construction comprising a frame, main springs mounted within the frame, and a set of longitudinally alining auxiliary springs slidably mounted at each end within the frame between the main springs.

4:. A spring construction comprising a frame, main springs mounted withinthe frame, a set of auxiliary springs slidably mounted within the frame between the main springs, and another set of auxiliary springs connected to the first mentioned auxiliary springs for cooperation with the latter to catch the extra weights.

5. A spring construction comprising a frame, main springs mounted within the frame, and longitudinally alining auxiliary arch springs slidably mounted at each end 6. A spring construction comprising a frame, main springs mounted within the frame, auxiliary arch springs slidably mounted within the frame, and another set of springs connected to the arch springs and disposed above the latter to cooperate therewith to catch the extra weight. 7

7. A spring construction comprising a frame, main springs mounted within the frame, and separate series of spaced longitudinally substantially semi-elliptical alining arch springs mounted within the frame to catch the extra weight.
